Accessing new regimes in quantum simulation requires the development of new techniques for quantum state preparation. We demonstrate the quantum state engineering of a strongly correlated many-body state of the two-component repulsive Fermi-Hubbard model on a square lattice. Our scheme makes use of an ultralow entropy doublon band insulator created through entropy redistribution. After isolating...

An interacting quantum system that is subject to disorder may cease to thermalize due to localization of its constituents, thereby marking the breakdown of thermodynamics. The key to our understanding of this phenomenon lies in the system’s entanglement, which is experimentally challenging to measure. We realize such a many-body-localized system in a disordered Bose-Hubbard chain...

Understanding strongly correlated quantum many-body states is one of the most thought-provoking challenges in modern research. For example, the Hubbard model, describing strongly correlated electrons in solids, still contains fundamental open questions on its phase diagram. In this work we realize the Hubbard Hamiltonian and search for specific patterns within many individual images of realizations...

The Department of Defense announced the selection of 11 distinguished faculty scientists and engineers to join the 2018 Class of Vannevar Bush Faculty Fellows (VBFF).

A research collaboration including CUA investigators at Harvard.

The BEC conference is a biannual meeting which is regarded the most prestigious and competitive conference in the field of atomic quantum gases, featuring about 45 invited presentations. Several CUA researchers presented invited talks:
